IMPROVEMENT IN TEMPLES FOR LOONIS.

Specification forming part 0f Letters Patent No. 2l ,5 l5, dated September 14, 1358.

To all whom, t may concern:

Be it known that I, ROBERT PILsoN, of Laurel, in the county of Prince George and State of Maryland, have invented certain new and useful Improvements in Temples for Looms; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification.

Figure l is a perspective view of the tem,- ple With the roller attached directly to the connecting-loar.` Fig. 2 is a perspective vier of the spring box or holder with its cap or covering detached. Fig. 3 is the tubular sheath. Fig. 4t is an ordinary wooden temple-roller. Fig. 5 is the adjustable connecting-bar and roller-spindle.

The nature of my improvements in temples consists in dispensing with the usual roller case or box and instead thereof employing an adjustable extension connecting suspension-bar, on each end of which is an independent tubular sheath orreceptacle for holding the pin-roller, and through all of which devices I produce what may be termed a double-actin g compensating spring-temple,7 which has free vibration to and fro horizontally, as Well as a yielding up-and-down motion simultaneously, the advantages of which will be more fully shown hereinafter.

In Fig. l, d a represents the breast-beam of a loom, and at l) l) are stationary spring-holders formed with an elongated slot in their bottom plate, as at c c, through which th ey are screwed into the top or upper part of the breast-beam, whereon they are adjustable to adapt them to varying Widths of cloth. 'lhe top of the spring-holder may be detached or hinged, so as to admit of ready access to its interior. At d is a cast projection formed on the spring-holder, and around this the coiled end of a detachable Wire spring e e e e is adjusted, the end f of which rests against the side of a catch-place g g, two of which catches may be cast or formed with the springholder.

Transversely through the'sides or Walls of the spring-holder, toward the front or broad end, are formed guide places or slots 7L h, and

Vin these is fitted a sliding yielding bracket or bearing-bar of t' 1f, having one end formed in shape of an oblong hook J J J, and at about one-third'of its length on the upper edge or face of the bar is a notch or nick 7;. At suitable distances apart on the top of the breastbeam the spring-holders are attached at distance from each other corresponding to the desired width of the cloth or fabric to be woven.

lVith i n the spriilg-holders are arranged the slidin yielding brackets or bearing-bars i.' vi1',

| the end of the wire spring e. e resting in the notch or nick 7.a, as shown in Fig. l. The pinrollers L L are shipped onto the shank-spindles m m of the adjustable extension connectingbars n. n, said bars being connected together by a slotted splice length o 0 0 0, Fig. l. This being done` the tubular sheaths P P q r are slipped onto the spindle-end m2 and over the pin-roller L, and its neck part q, being bored with a cylindrical opening yr, the tubular sheaths arc held firmly by tightening-screws s s. Thus the rollers are connected together by the bars n n and splice-lengths o o 0 0, and shank-spindles m2 m2 rest in the hooks J J J J of the sliding yielding bracket or bearingbar i t' t.

It willbe'observed that the temples are separate and distinct and independent of any direct connection with the breast-beam of the loom and are detachable at one and the same time instead of being connected with different separated cases or temple-boxes.

I am well aware that a patent was granted August 7, 1855, to James Smith and lVilliam Batterville for improvements in temples, wherein a solid individual rod or bar is employed suspended in slotted brackets, said rod or barbearing up laterally against aixed flexible strip of metal. To the ends of this solid individual bar or rod temple-cases are attached by their heel parts and not the pinrollers, as is the mode in my improvements, wherein my pin-rollers are attached directly to the ends of an extension bar or rod, Whereby the necessity of employing adjusting and tightening sustaining-screws to prevent the temple-case from falling forward is overcome, and the danger of disarrangement of the pinroller and its sheath with the pressure for- Wa rd thereof is greatly obviated. In the abovealluded-to patent the solid bar or rod is not susceptible of extension and adj ustability in its longitudinal direction so as to be adaptable to varying widths of cloth; but my devices do present this most important feature of improvement.

In the operation of my temples they are governed wholly and solely Vby the motion of the cloth which passes around, under, and beneath the rollers, as shown or indicated by the arrows, and consequently the temples, with the bar n yn and splices o o o 0, rest on top of the cloth, and the blow of the lay of the loom does not in any way act on the temple. Consequently much power is economized, while all concussion or shock is prevented, the action of the heddles, together With the tension of the cloth, imparting to the temples an equable and sufficiently-yielding action. The ends of the spindles, being disconnected, Work perfectly free up and down in the hooks J J J. The motion of the warp up and down, and technically termed the shades of the cloth, causes the up-and-down yielding or accommodatng motion of the temples, thereby admitting of com pensat-ing the tension of the cloth, while at the same time the temples have a horizontal yielding action through the agency of the devices i t' z' and their springs e e e e. Thus is all rigidity or stiffness of action of the temples overcome.

Another most important feature pertaining to my improvements is that the construction and arrangement of parts are such that little or no lubricating matter is required, the use of which mostgenerally tends more or less to soil the cloth.

An additional improved feature is the very great facility with which the sheaths P P q fr, Fig. 3, canbe detached separatelyand independently of the rollers, thus admitting of ready substitution of rollers.

Having given as full and explicit a description of my improvements as is deemed essential, what l claim as new and of my own inven` tion, and desire to have secured by Letters Patent of theUnited States, is-

The construction of temples for looms, wherein is employed an adjustable extension,

compound connecting bar or rod composed of the spindle bars or sections m2 121,211 n and the splice lengths o o o o, the detachable independent tubular sheaths P P q r s, Fig. 3, the sliding yielding brackets or bearings t' fr' z' J J J, spring-holders b b, and springs e e. e, the whole operated as shown, and whereby a double yielding action of the temples is brought about, and for the purposes substantially as herein set forth and described.
